Lasers Approach Their Ultimate Intensity Limit
Flash Modin writes "Death Star style superlasers? Don't bet on it. High-power lasers currently in development appear to be nearing the theoretical laser intensity limit, according to new research set to be published in the journal Physical Review Letters. Ultra-high-energy laser fields can actually convert their light into matter as shown in the late '90s at the Stanford Linear Accelerator (SLAC). This process creates an 'avalanche-like electromagnetic cascade' (also known as sparking the vacuum) capable of destroying a laser field. Physicists thought it might be a problem for lasers eventually, but this work indicates the technology is much closer to its limit than researchers believed. A preprint is available here."
Uhm, because you just cause the existing matter to change forms. Let me simplify it to something that you can probably understand ...
You can make water from hydrogen and oxygen gas ... does that mean matter is being created? No, its changing form. Not EXACTLY the same thing, but just because you misunderstand how it happens doesn't mean it doesn't happen in a particular way.
Until you can explain to me how the universe was created, why it exists and what exists outside of the universe then you clearly don't understand the way it works so trying to claim you know how individual bits work is ... ignorant at best. Before someone trys to explain it like they know how the universe works, just stop, you really don't.

Hey mods, eat my feces for modding me down. That's right, suck it right out of my anus. I know that you love felching.
